New Delhi: Delhi Police investigating the Sunanda Pushkar death case on Thursday said it may question Pakistani journalist Mehr Tarar over whom she fought with her husband Shashi Tharoor before her death last year.

Delhi Police Commissioner B S Bassi said Tarar may be questioned, if required, as she may throw light in the case.

"If required, we will speak to her as she is a relevant person who can throw light in the case. Our efforts will be to talk to her," Bassi said when asked whether the SIT probing the case will examine her.

Sources in the police said that a formal request may be sent to her through "official channels" to join the investigations.

Tarar had two months back said that she was ready to answer any question on the issue.

"If they want to ask me anything...If they want to ask me any question whatsoever that they think...I can answer," 46-year-old Tarar had said a day after Delhi Police had registered a murder case into Sunanda's death.

52-year-old Sunanda was found dead in her suite at a five star hotel in south Delhi on the night of January 17 last year, a day after she was involved in a spat with Tarar on microblogging website Twitter over the latter's alleged affair with Tharoor.

Tharoor was questioned by the investigators last month.

Bassi said investigators have also asked the Federal Bureau of Investigation (FBI) in the US to complete examination of Sunanda's viscera as soon as possible.
